2 SHEETSSHEET 2- JOSEPH. H. MURRAY, OF HOMER, GEORGIA.

FORGE.

To all whom it may concern:

Be it known that I, JOSEPH H. MURRAY, a citizen of the United States,residing at Homer, in the county of Banks, State of Georgia, haveinvented a new and useful Forge; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to an improved forge, and one of the objects ofthe invention is to provide means whereby a blast of air may be forcedinto the forge, to cause the fire to burn.

Another feature of the invention is to provide a slide plate havingapertures to cooperate with the apertures of the tapering outlet of theblower, to regulate the blast of air to the forge.

Another feature of the invention is the provision of a deflector fordeflecting the blast of air toward the bottom of the fire of the forge,in orderto cover the full area of the fire.

In practical fields, the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings, and claimed.

In the drawings Figure 1 is a view in side elevation and partly insection of a portion of the forge pot, showing the motor driven blowerapplied.

Fig. 2 is a sectional view through the forge pot and through the motorfor driving the blower, which is shown partly in elevation.

Fig. 3 is a sectional view on line 3-3 of Fig. 1.

Fig. 4, is a detail view in side elevation showing the spring tensionedgear of the spring motor.

Fig. 5 is a detail view of the spring dog for engaging a ratchet wheelon the shaft of the spring tensioned gear for preventing the spring ofsaid gear from unwinding when once wound.

Fig. 6 is a detail sectional view through the end of the arm or lever 13of the rod 11, showing the spring tensioned pin 14.

Referring more especially to the drawings, 1 designates the casing ofthe blower, in arings f hi h a shaft 2 is m unt d Specification ofLetters Patent.

Application filed November 2, 1916. Serial No. 129,166.

Mounted upon the shaft 2 is the hub 3 of the wheel 4, by the operationof which wheel, a substantially continuous blast of air is generated andforced through the tapering part 5 of the blower casing. This taperingpart 5 of the blower casing extends through the wall 6 of the forge pot,and has an apertured or perforated end wall 7, with which the apertures8 of the slide 9 cooperate, in order to regulate the amount of airdischarged into the forge pot. The slide 9 is mounted in the guides 10.

It is to be observed that by adjusting the slide in one direction or theother, the apertures 8 of the slide can be made to entirely.

register or partially register with the apertures in the end wall 7, inorder to regulate the discharge of the blast. Mounted in suitablebearings on the wall of the forge pot is a rock shaft 11, on which adeflector 12 is carried. This deflector is curved so as to extend downover the apertured slide. iVhen the rod 11 is adjusted to throw thedeflector down, the blast of air will be deflected and caused to spreadover the whole bottom of the fire of the forge. Should the deflector bemoved to extend upwardly, by rocking the rod 11, the blast of air willextend more through the top of the fire of the forge. One end of the rod11 has an arm 13, in an end of which a spring tensioned pin 14 ismounted, to engage any one of the depressions, 15, to hold the shaft orrod 11 in different adjusted positions.

The shaft 2 is mounted in suitable bearings 16 and 17 of the casing 1,one side ofv mounted. The shafts 22 to 25, inclusive, are

provided with gears 27 to 34, inclusive, which mesh, as shown in Fig. 3,and are keyed to said shafts. The gear 27 meshes with a gear 35 on theshaft 2. Loose upon the shaft 26 is a gear 36, which meshes with thegear 33 of the shaft 25. Integrally formed on one side of the gear 36 isan annu ar f ange 7 f rm ng a ca ing f r spring 38, one end of which issecured at 39 shaft 26, in other words, prevent the spring 3.8;fron1unwinding after once havlng been wound. One'end of the shaft26 hasacrank 44secured to it as at 45, whereby the shaft 26 may be rotated forwinding the spring. Secured by suitable pins-46 to the shaft 26 alfecollars .47, between which the collar 48 of the pawl or dog 49 ismounted, so the pawl or dog 49 will engage the teeth of the gear .34,thereby preventing the (chain of gears from operating under the actionof the Spring 38. The pawl 49 has a laterally extending pin 50 extendingthrough a slot 5.1 Qfoneof the side walls of the casing 21, and bygrasping this pin, the pawl may be thrown out of engagement with theteeth of thegear 34, thereby leaving the gears free to move or rotateunder the tension or the action of the spring 38, thereby impartingmovement to the blower, which will force the blast of air through thetapering part 5 of the casing l. The casing 21 has a suitable cover 53,which may be removed to permit access to the interior of the casing 21,for oilingand repairing the gears. The slide has an extension rod 52extending through the wall of the forge and provided witha handleCamelot this patent may be obtained for 54, wgiereby the slide may bemoved or aduste The invention having been set forth, what is claimed asnew and useful, is

1. In a forge, a blower having a tapering part extending through thewall of the forge and having a discharge passage, theend of said taperedpart having perforations, the wall of the forge having guides at the topand bottom of said end, a slide mounted in the guides and havingperforations, :and

adapted to move on and against said end,

whereby the perforationsof theslide may cooperate with .theperforations-of theendfor regulating the blast iOf air into the forge,and a deflector pivoted in the wall of the forge for deflecting theblast of air as :it .passes through the perforations :of the end and theslide. 7

2. 111a forge,.a :blo-wer having-a ,tapering discharge nozzle extendingthrough the wall of the forge and provided with .means s'IEOl regulatingthe blastof air :into the forge, a deflector pivoted in the wall -.-ofthe forge and adjustable to extend down over :said means, whereby theblast of air :may be deflected downwardly. In testimony whereof I havesigned my name to this specification in the presence of threesubscribing witnesses.
